CARL BABTELS, OF HAMILTON, OHIO, ASSIGNOR TO THE MOSLER- SAFE COMT ANY,OF NEW YORK, N. Y.

SAFE OR, VAULT \VALL.

T0 (ZZZ whom it may concern Be it known that I, CARL BARTELS, a citizenof the United States, residing at Hamilton, Butler county, Ohio, haveinvented certain new and useful Improvements in Safe or Vault lValls, ofwhich the following is a specification.

This invention, pertaining to the construction of the walls of safes orvaults relate-s particularly to such safes or vaults as are composedmainly of unmachinable metal, such as manganese steel, the aim of thepresent invention being to provide the exterior of the wall,particularly the wall containing the door-opening, with means by whichhinges etc., may be conveniently at tached.

The invention will be readily understood from the following descriptiontaken in connection with the accompanying drawing in which Figure 1 is afront elevation of the front wall of a round-door safe, portions of certain front-work being broken away to more clearly illustrate theconstruction; and F 2 a horizontal section, upon an enlarged scale,through the door-jamb in the plane of line a of Fig. 1.

In the drawing:-l, indicates the front wall of a safe assumed to be ofunmachin able metal; 2, the door-opening therein illustrated as beingcircular as is usual in safes made of the material in question; 8, thesteps of the door-jainb; f, a shallow recess formed in the entire frontof the all except as to the margins hereinafter referred to; 5, theouter margin of the recess, this mar gin forming also the margin of thewalls; (3. the inner margin of the recess, this margin surrounding thedoor-opening; 7, studs projecting from the safe wall into the recess,these studs being formed integrally with the metal of the wall andhaving a length substantially equal to the depth of the recess; 8, aplate of machinable metal disposed within the recess, and preferablyfilling it, this plate being provided with apertures e11- gaging studs7, the outer ends of which studs are riveted after the plate-is inplace, 7 indicating the studs in unriveted condition; 9, the studs inriveted condition, and 10, a mask-plate secured against the outer faceof the plate and margins, as by means of screws passing through themask-plate and threaded into plate 8.

lVhile manganese steel cannot be cut it can be ground and it can beriveted. Plate 8, having been fitted to the recess and studs, the studsare then riveted at the front face of the plate, thus practicallyunifying the plate with the wall. The masleplate, which may be of anymachinable metal and as ornamental as desired may then be applied toplace, covering the riveted ends of the studs. Owing to the fact thatthe edge joints of the plate are covered by the maskplate it is notnecessary that the plate lit with any special accuracy or nicenessagainst the margins of the wall. Hinges etc., may be secured to theplate by the usual system of screws, owing to the fact. that the platemay be drilled and tapped, and it will readily be understood that forthis purpose the plate need not be applied over the general surface ofthe wall but only at such portions of the wall surface as required to bedealtwith by means of cutting tools. Hinges, etc.. may be securedagainst the mask-plate by means of screws passing through the mask-plateand into the riveted plate. or they may be secured directly to theriveted plate, the mask-plate being suitably notched to permit this.

The riveted plate may be permanently secured in place and then thehinges etc., may be secured to it, as has been indicated. or, ifpreferred, the riveted plate may be fitted to place and the rivetingomitted, after which the plate may be removed from the wall and fittedup with hinges etc, after which the plate may be returned to place andthe riveting done and the mask-plate applied.

I claim 1. A safe or vault wall con'iprising, a wall consisting ofunmachinable metal, studs in tegrally formed with the wall and projecting from its front face, a plate of machinable metal having perforationsengaging said studs and secured to the wall by riveting the studs at theouter face of said plate, and a mask-plate secured to the outer face ofsaid perforated plate, combined substantially as set forth.

2. A safe or vault wall comprising, a wall consisting of unmachinablemetal provided with projecting margins to form a facial recess, studsintegrally formed with the wall and projecting from its front face intosaid recess, and a plate of machinable metal disposed Within said recessand having perforations engaging said studs and secured to the Wall byriveting the studs at the outer face of said plate, combinedsubstantially as set forth.

3. A safe or vault Wall comprising, a Wall consisting of unmachinablemetal provided With projecting margins to form a facial recess, studsintegrally formed with the Wall and projecting from its front face intosaid recess, a plate of machinable metal disposed Within said recess andhaving perforations engaging said studs and secured to the Wall byriveting the studs at the outer face of said plate, and a mask-platesecured to said perforated plate and covering the joints between saidmargins and the edges of said plate, combined substantially as setforth.
